The collisions of rigid bodies is a classical problem, however, the coefficient of restitution is used in the conventional researches to study this problem. The authors present a new way for this kind of problem. A theory of the collision between two rigid bodies in two dimensions, taking account of friction, is proposed according the Newton first law. And the shortages of former researchers are justified.

At first, the examples are given to explain a new method in signal processing, in which functions are defined from the viewpoint of multi-scale analysis. Then the authors present "coordinate heft separate" method, discover self-similar structure of points set on plain area; based on this self-similar structure, construct orthogonal complete 2-value function system of high-dimension simplicity; enrich and extend the theory and application of Rademacher function and Walsh function.

首先，举例说明在多尺度分析观点下，信号处理中某些函数定义的新方法；进而提出"坐标分量分离方法"，并由此发现了平面区域上点集坐标数值的自相似结构；在揭示了如此自相似结构的基础上，构造了高维单纯形上的正交完备的二值函数系统；丰富与推广了Rademacher函数及Walsh函数的理论及应用。

First of all, confirm the overall evaluating indicators and the base indicators of public transport network in Chinese large cities through repetitive comparison, discussion and consultation to relevant experts; among the base indicators in the overall evaluating indicators, composite the basic probability assignment of evaluation indicators with Dempster-Shafer Theory composition rule upon different experts' experiences and preferences of the expert group, and amalgamate the evaluations of different experts to further obtain the evaluation value of base indicators.

首先通过反复比较、探讨和征询有关专家的意见，确定大城市公交线网综合评价指标及子指标，在综合评价指标的子指标中，对专家组中不同专家的经验和偏好，用证据理论合成规则对评价指标的基本概率赋值进行合成，将不同专家的评价进行融合，获得子指标的评价值，然后通过突变理论将评价指标及子指标作为控制变量进行地面公交线网的综合评价，对北京市进行算例分析结果表明，该方法对大城市公交线网的综合评价是可行。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
